Receive a binary in the kafka wire format and deserialize it into a map.
Response content fields:
- throttle_time_ms: The duration in milliseconds for which the request was throttled due to a quota violation, or zero if the request did not violate any quota. (int32 | versions 0+)
- error_code: The error code, or 0 if there was no error. (int16 | versions 0+)
- client_instance_id: Assigned client instance id if ClientInstanceId was 0 in the request, else 0. (uuid | versions 0+)
- subscription_id: Unique identifier for the current subscription set for this client instance. (int32 | versions 0+)
- accepted_compression_types: Compression types that broker accepts for the PushTelemetryRequest. ([]int8 | versions 0+)
- push_interval_ms: Configured push interval, which is the lowest configured interval in the current subscription set. (int32 | versions 0+)
- telemetry_max_bytes: The maximum bytes of binary data the broker accepts in PushTelemetryRequest. (int32 | versions 0+)
- delta_temporality: Flag to indicate monotonic/counter metrics are to be emitted as deltas or cumulative values. (bool | versions 0+)
- requested_metrics: Requested metrics prefix string match. Empty array: No metrics subscribed, Array[0] empty string: All metrics subscribed. ([]string | versions 0+)
